US 2022/0026781 A1 · IMAGE ACQUISITION APPARATUS, ELECTRONIC DEVICE, IMAGE ACQUISITION METHOD AND STORAGE MEDIUM

Abstract

An image acquisition apparatus includes a camera, a flash array adjacent to the camera, and a flash driving circuit connected to the flash array. In the process of image acquisition based on the image acquisition apparatus, a driving signal provided by the flash driving circuit may be used to drive corresponding flashes in the flash array to be lighted, a driving current for controlling each of the flashes may be adjusted to control the brightness of a respective one of the flashes. The number of lighted flashes in the flash array or the light supplement brightness of the lighted flashes may be adjusted adaptively according to different shooting scenes.
